For finding the diameter of the circle of the given equation (x-4)^2+(y+6)^2=16
We compare this equation by the circle of the equation that is x^2+y^2=r^2
we get the value of " r" is 4 which is the square root of 16.
We know that the diameter of the circle is twice the circle's radius so the diameter of the given equation is 2r=2*4=8
Option( c) is correct.
